This research aimed to compare the water quality of koi fish ponds and Nile tilapia ponds in Yan Ta Khao District, Trang Province. The objectives were: 1. to study the water temperature of koi fish ponds and Nile tilapia ponds, 2. to compare the water transparency of koi fish ponds and Nile tilapia ponds, and 3. to compare the dissolved oxygen levels in koi fish ponds and Nile tilapia ponds. The parameters studied included water temperature, water transparency, and dissolved oxygen content. The results showed that the average water temperature of the koi fish pond was lower than that of the Nile tilapia pond, with an average temperature of 25 degrees Celsius. The water transparency of the koi fish pond was higher than that of the Nile tilapia pond, with an average value of 83.3 centimeters. In addition, the dissolved oxygen level in the koi fish pond was higher than that of the Nile tilapia pond, with an average value of 4.5 milligrams per liter. Keywords: water quality, koi fish pond, Nile tilapia pond
